Joule Thief

[unzapped]

It actually went really well! I am sending him some coil specs... and he is giving my Unzapped cell to his electrical engineer for further study... He seems to think he will be able to tell me which toroid material will give the best performance. For the time being he is going to get me some toriods based on whatever specs I provide him. Their winding machines are really awesome... I could live in that factory. So much stuff!... He was the one that said why wouldnt you just do that with a transformer, and asked what makes the thief so special... lol
I think within week or so he will give me a coil to my spec and windings to play with... they didnt have ferrite in stock in those sizes... but they had LOTS of ferrite, tape wound, iron and nickel powdered toroids a host of other material which would take a machine to wind...

Cool place for sure!

Thanks

SIR WILL AND SIR SPARKS


MOST WICKET POSTS! 

btw i picked up some CAUTION TAPE FOR MY RINGS .....  to serve as a warning as well to hold the wires ...

j

lol 

you gonna love me even more ... 


lol 

i bought 2 cfls brand new ...   and im a magic make em  big time

unit

2 cams ... 2 aaa..  2 cfls ...  2 mots ... 

kitty kitty  bang bang!

ist!

: )

all left hand of course ...  ; )

FOR J  a pic of a riddle my mother left me last time i saw her!! 

its for j ...  cuz only a few know what i speek of ...

It sounds like it.
Skip the powdered ones for now. We have had low results. We may crack their puzzle, but have not done so yet.

Have a look at the website for MMI

Then look at the toroids called
0W48613TC - that is the big gold. It is the W type 3.3inch toroid that gave me 2000 volts.
0W46113TC - that is the 14,000u one from the hairpin circuit video I made the other day.
0J46113TC   - that is the same size as above, 11,000u I mentioned that almost does it, but not quite, and I don't know why not.

This will give you, and maybe your friend a start on knowing what we need, but we do not need just these.
I really think what we need is skill.

I have been using an unknown one that is 3/4 inch but has been giving me 500-900v... even lit a fl tube.
I am actually scared it will fry today's project, so I am backing off to use one of my earliest little toroids. I am making a grow light using leds today, and, I will be experimenting with the growth differences as this winter progresses.

@wilby,
I love your icefishing tale.
That 12 year old's water pipe battery looks really cool.
I have not been able to make that kind of battery last more than a few days. Not because of the electrolyte so much, but because the metal gets crud.
Stephan offered a cool battery 2 years ago.
It was a graphite carpenter's pencil and alu foil.
I needed 2 in series and it lit a led for many days... until the alu foil became black I assume with carbon.
It is really a good thing to have one or 2 of these kinds of batteries around for dire emergencies, but have you ever given them a longevity test?
Like a 23 walleye battery? = how long it takes to catch 23?

thanks ,

Maybe for your caps, but last night after all those cautions, my 1000v dropped to 44v with the diode and cap, but it was OK, and rose back up to 1000v after I removed the diode and cap.

BAAH!
no tape needed, but your caps probably could cause a burn.

The problem with those big caps of yours is that it is not an easy thing to put a cap like that on the shelf along with a lamp.

This is great fun, but not too practical yet.

How small a cap will allow you to light an unmodified cfl?
That is interesting to me, because someone can actually use it and not need the wall power.
See?

thank you,

baby GET READY ...

100w light bulb from a b cap and cam boards 1 aa ...  bet it runs a long time ..... 


lol 

probally get hot too might burn your hand ....  DID I SAY 1  OR 10?   lol  does it matter much

lol

love ya ...

awaiteing B CAP ..  THEN VIDEO TIME ......

lightS  camea Action!
